IT之家日前参与了宝马在南京举办的智能驾驶辅助全国首次公开道路试驾活动。1本次试驾于9月21日进行，路线约25公里，覆盖城区、高架、隧道及紫金山周边连续弯道等多种路况。1试驾对象包括新世代BMW i3和iX3，两款车型均搭载由宝马与Momenta深度共研的智能驾驶辅助系统。1
该系统基于Momenta R7世界模型，采用超过150亿公里中国真实道路数据和1.68亿段黄金场景进行开发，日均虚拟训练达1000万公里。1宝马强调这套系统遵循人机共驾、无缝衔接的驾驶理念，保留驾驶者的参与感和驾驶乐趣。1从配置层面看，新车搭载17.9英寸液晶显示屏，屏幕向驾驶员旋转17.5度，使操作距离缩短50毫米；视平线全景显示宽度达1.2米。1新世代i3轴距加长108毫米，并采用电机扭矩控制制动，刹车盘可实现10万公里无需更换。1BMW采用"一车一调"策略，针对每款车型进行专属适配和精细调校。1
BMW held its first national public road trial of an intelligent driving assistance system in Nanjing on September 21st.1 The event showcased the new-generation BMW i3 and iX3 equipped with an intelligent driving assistance system developed through deep collaboration between BMW and Momenta.1
The trial route covered approximately 25 kilometers, traversing urban areas, elevated highways, tunnels, and continuous winding roads around Zhongshan Mountain.1 The system is built on Momenta's R7 world model and leverages over 150 billion kilometers of real Chinese road data along with 1.68 million golden scenario segments.1 It undergoes 10 million kilometers of simulated daily training.1 BMW emphasizes a "one car, one calibration" strategy, with intelligent driving assistance customized and fine-tuned specifically for each vehicle model.1
The system reflects BMW's philosophy of human-machine co-driving and seamless transition, prioritizing driver engagement and driving enjoyment.1 The new models feature a 17.9-inch liquid crystal display that rotates 17.5 degrees toward the driver, reducing operational distance by 50 millimeters.1 The panoramic vision display spans 1.2 meters in width.1 The new i3's wheelbase has been extended by 108 millimeters.1 Additionally, the braking system's brake discs require no replacement for 100,000 kilometers through motor torque control braking.1
